I do review the regression test results before posting the source bundles; however, as you've observed not all the tests pass currently. Over time, the fraction of failing tests as well as the total number of failing tests have decreased. Prioritizing addressing the test failures is generally done by the teams in the affected component area; for example in b13 we resolved all failing langtools tests (as well as made those tests runnable in the much faster "same vm" mode). Most of remaining failures are in AWT and 2D.
